OP fluctuates throughout the range, as the oil heats up the general trend is downward. A manual gauge on the same engine shows a general deterioration down to about 18lbs 'inch at 1500revs, but is not sensitive enough to show the variations. I wonder if with the logger sampling so often per second there is some sort of electrical bounce going on!
